HANGING WINDOW-SASH.

Specification of Letters Patent No.

To all whom 'it may concern:

Be it known that I, T. F. HALL, of Marietta, in the county of Washingtonand State of Ohio, have invented a new and Improved Mode of BalancingSash in lNindows; and I do hereby declare that the following is a fulland eXactdescription thereof, reference being had to the accompanyingdrawings, making a part of this specification, in which- Figures l and 2are respectively ver ical and horizontal sections of a common windowframe and sash. Figs. 3 and e are respectively vertical and horizontalsections of a box window frame and sash.

Similar letters of reference indicate corresponding parts in the severalfigures.

F represents the window frame; T, the upper sash; L, the lower sash; C,the cord supporting sash T; K, the cord supporting sash L; P P P,pulleys on the window frame; G, grooves in the sashes; R, pulleys orfriction rollers in the groovesI in the sashes; I, the point where thecord O is attached to the frame; J, the point where the cord K isattached to the frame; VV, weights attached to cords C and K; W, weightin box frame.

The construction and operation will be readily understood.

Grooves are cut in the stiles and lower rails of the sashes ofsufficient size to receive the cords. In these grooves at the lowercorners of the sash are placed the pulleys or friction rollers R R R R.

Pulleys P P are attached to the window 22,365, dated December 21, 1858.

frame near the top corners thereof as shown in the drawings.

In common frames the cord ,O is fastened to the frame at I passes in thegrooves of the upper sash beneath the pulleys R R and over pulley P andis attached to the weight IV. The cordvK is fastened to the frame at J,passes in the grooves of the lower sash beneath the pulleys R R, overpulley P and is attached to weight IV. In box frames the cord may befastened at I (Fig. 3) pass beneath the pulleys in the upper sash, overa pulley near the top of the box frame, beneath a pulley in weight lover another pulley near top of box, through the grooves and beneath thepulleys in the lower sash and be fastened in frame at J. Or ifdesirable, instead of the weight lV, two weights in the box may beemployed having separate cords attached permanently to each of them.

It will be seen that by this arrangement the sashes are suspended on thecords and balanced by the weights or a weight, and can be raised andlowered at pleasure.

1What I claim as my invention and desire to secure by Letters Patent is-The employment` and arrangement of pulleys or friction rollers at thelower corners of sash and the balancing of the sash on cords incombination with pulleys and weights or a weight substantially as aboveset forth.
